‘Modernitat Amagada’ organised by ACM (Associació per a la Cultura i l’Art Contemporani de Mataró), was a short-lived group show at Casa Capell in Mataró, the wonderful former home of the Masjuan family. It was built in 1959 by Jordi Capell (1925–1970), a little-known rationalist architect, mathematician and humanist.
